T0 rel Z w/w'm it Tmmy concern.-

Be it known that 1, CHARLES EDMUND PEG- ZENIK, a subject of the King of Great Britain, residing at 53 Portland Place, London, VV., England, have invented certain new and useful Improvements in Hand-Cameras, of which the following is a specification.

Twin-lens and reflector cameras generally have been hitherto of a bulky nature.

The object of this invention is to reduce the size of cameras of the reflector type to make them more. portable and convenient to use. The novel feature of this reflector-camera is that it is so constructed that when not in use it may be closed up in a comparatively small compass.

In the accompanying drawings, Figure 1 is a longitudinal section of one form of handcamera constructed in accordance with this invention. Fig. 2 is a back view of the same, and Fig. 3 is a perspective view of the same.

like letters indicate like parts throughout the drawings.

Between the lens-board A, which carries the lens, and the back of the camera B, which carries the plate or film, is fixed a bellows or gusset C. The lens-board A in its extended position is held open by distance-bars D, pivoted to the back B and engaging pins A on the lens-board. When the camera is not in use, the lens-board A can be brought near the back B, the gusset C and the focusing-hood E folding up at the creases C and E and allowing'the body to collapse, the distance-bars D turning into theback B.

The focusing-screen F is carried on a spindle F, journaled in the sides of the cameraback B. The spindle is provided with a milled knob F outside the case on one side, whereby the screen F may be turned, and stop F on a leaf-spring F on the back B is arranged to engage a recess F on the knob F when the screen F is turned into a horizontal position for focusing, as shown in full lines in Fig. 1, and when it is desired to collapse the camera the screen is turned into a vertical osition in the back of the camera, as shown in dotted lines in Fig. 1. The point of a tool,

knife, or the finger maybe pressed inwardly against the spring F in order to disengage the stop F thereof from the recess F The reflectingmirror G is attached to a plate G, which is bent twice at right angles,

and is carried on a spindle G journaled in two bearings H in a frame H, pivotedon a cloth, metal, ,wood, or thelike.

rod J, supported in the sides of the camera. The frame 11 normally rests on a fixed cradle K, connected with the rod J 4 and with the sides of the camera. Within the cradle is a pneumatic bulb K, connected by an air-tube K with a pneumatic hand-ball K and when the ball K is pressed and the bulb K expanded the frame H is tilted upward about the rod J and carries with it the mirror G,

which is thus moved out of the path of the rays from the lens.

'The mirror-plate G is normally held flat against the frame H by means of a spring 9 or the like; but when the focusing-screen F is turned down in a vertical position it carries the mirror'G with it, as shown in the dotted lines in Fig. 1, so that the body 0 of the camera is free to collapse.

The shutter is of the focal-plane type. It comprises an upper blind L on a roller M and a lower blind L on a roller N, the two rollers being connected by an elastic band 0 or otherwise. The lower roller N contains a spring N, which tends to pull the blinds down. The spindle of the upper roller M has a milled knob M outside the camera, whereby the blinds L L may be turned up onto the upper roller M, and a toothed wheel M on the end of the roller-spindle is normally prevent- I ed from rotating backward by a pivoted pawl P, controlled by a spring P. The tail end of the pawl P su ports a light rod Q, which can slide in gui es Q, and the upper end of the rod Q is arranged in the path of a projection H on the frame H, so that when the frame H is tilted up by the pneumatic bulb- K the projection H presses down the rod Q against the action of the spring P, and

thus releases the toothed wheel M and allows the spring N" to pull .down the shutter onto the lower-roller N.

The body of the camera may be of leather,

The focusing-screen may be of any known type. A

' Having now particularly described and ascertained the nature of my said invention and in whatmanner the same is to be performed, I declare that what I claim is 1. In a reflector-focusing camera, the combination of the cameraback, focusing means foldable into the camera-back, and a collapsible body portion carrying the lens-board and foldable onto the camera-back.

2. In a reflector-focusing camera, a collapsible body portion interposed between ioo focusing-screen and reflector movable intoand out of said bod' portion.

4. In a reflectorocusing camera, the combination of the camera-back, the collapsiblebody ortion carrying the lens-board, a collapsib e focusing-hood carried by the body portion, a focusing-screen movable from a position beneath the hood into the camera back, and a reflector normally lying beneath the screen and movable into and out of the cameraback.

5. In a reflector-focusing camera, a collapsible body portion carrying a focusinghood, a yieldingly-supported reflector, and a focusingescreen arranged to move against the {)efiictor and carry the same into the camera- 6. In a reflector-focusing'camera, a col lapsible body portion carrying at the top a focusing-hood, a normally horizontal focusing-screen arranged beneath the hood and supported to swing into and out of position, a

normally inclined reflector-mirror yieldingly supported in the path of movement of the screen, and a reflector-positioning device.

' 7 In a reflector-focusing camera, the body portion, the focusing-screen, a swinging sup porting element, a normally inclined reflector having a pivotal connection with said sup orting element, a pneumaticallycontrollbd positioning device 0 crating against said supporting element, an means for movin the reflector into the back of the camera.

in Witness whereof-I have hereunto set my hand in presence of two subscribing witnesses.

CHARLES -E. PECZENIK.
